Evaluation of clock function and accuracy of CYCLOPS ordering in epidermis and dermis. A heatmap of Spearman’s rho for clock and clock-associated genes from longitudinal (n = 20, Additional file 1: Table S1) and population-based data (n = 154, Additional file 1: Table S1) is shown for epidermis (a) and dermis (b). The population-based epidermis or dermis samples are from the forearm, cheek, and buttock of the same 154 participants. The longitudinal order of samples collected from 20 participants was accurately recalled in epidermis (c) and dermis (d). Different colors indicate different participants, and the circular average phases for all samples are shown in gray at each sampling time. Samples from participants 116 and 119 are indicated by triangles
